Unformatted text preview: or some media, the propagation velocity follows from: Pressure waves in a liquid or gas: v = / , where is the modulus of compression. or pressure waves in a gas also holds: v = p/ = RT/M . Pressure waves in a thin solid bar with diameter << : v = E/ waves in a string: v = F span l/m Surface waves on a liquid: v = g 2 + 2 tanh 2 h where h is the depth of the liquid and the surface tension. If h holds: v gh . 5.2 Solutions of the wave equation 5.2.1 Plane waves In n dimensions a harmonic plane wave is deFned by: u ( x,t ) = 2 n u cos( t ) n i =1 sin( k i x i )...
